  • Apache: scope for environmental variables

    - by Anonymous
    While there's documentation available on Apache environmental variables, I can not find answer to one important question. Imagine I use rewrite rules to set environmental variable RewriteRule ... ... [E=something:1] What is the scope of "something" - global Apache server (this means "something" will be available for other request transactions), this request (means that "something" is only valid for THIS http request (and its related processing - but what's about internal redirects and other internal stuff - are they considered as THIS request, or another one?), and may be set differently within another (concurrent) request?

  • iPhone development: Best method to allow user to chose search scope

    - by Mark Pemburn
    Hi, I'm developing my first iPhone app and want to allow the user to select the scope of their search in a more complex way than the 'scope buttons' permit. The app is related to wines and I want to the user to be able to select the 'color' (Red, White, Blush, etc.) first, and then select the type/varietal within that category. Right now, I'm using the UISearchBar's scope buttons for the colors and tapping the button opens a view with the selection of colors. This is okay except that once the 'Red' button has been selected, I can't select it a second time to change my choice of type (e.g., change from 'Merlot' to 'Syrrah', etc.) If there's a better way to do this, I'm willing to scrap my method and start from scratch. Thanks!

  • How to call angular javascript directive methods from the global scope

    - by user1659278
    I have a directive like the one of the examples from AngularJS, shown below. How can I call the toggle method from the global scope? I want to be able to toggle the zippy from some legacy code. myApp.directive('zippy', function(){ return { restrict: 'E', replace: true, transclude: true, scope: { title:'bind' }, template: '<div class="zippy">' + '<div class="title">{{title}}</div>' + '<div class="body" ng-transclude></div>' + '</div>', link: function(scope, element, attrs) { var title = angular.element(element.children()[0]), opened = true; title.bind('click', toggle); function toggle() { opened = !opened; element.removeClass(opened ? 'closed' : 'opened'); element.addClass(opened ? 'opened' : 'closed'); } toggle(); } } });

  • "session" bean scope in a web application - reliable ?

    - by EugeneP
    Can you rely on this scope and be sure that every time 1) a new session starts, the Spring bean will be initialized with default values 2) while session is kept alive, the current object will store its state during session life, will never be lost or corrupted and can always be got with [webappcontext].getBean ?

  • Using scope, defined in parent model, inside it's child (STI pattern)

    - by Anton
    I implement a class hierarchy using STI pattern class A scope :aaa, where([someField]:[someValue]) end class B < A end The problem is that when I try to call something like: B.limit(5).aaa => SELECT "[table]".* FROM "[table]" WHERE "[table]"."type" IN ('A') AND ([someField] = [someValue]) LIMIT 5 So I am getting 5 objects of type A, which satisfies scope :aaa But I need to do the same with rows where type = "B" Is there any way to use scopes from parent, without redifinning it in childs in STI pattern? Thanks in advance EDITED I just discussed it with my frind and he showed me one important thing. A in not the root class of STI. IN fact whole hierarchy looks like class O < ActiveRecord::Base end class A < O scope ..... ..... end class B < A end maybe the reason is in hierarchy itself?...

  • Rails Scope for association of 0 size.

    - by MissingHandle
    I'm having trouble figuring out the scope method for all the Foos that have no Bars. That is: class Foo < ActiveRecord::Base has_may :bars end class Bar < ActiveRecord::Base belongs_to :foo end I'd like to write a scope method that returns me all the foos that have no bars. Something like: class Foo < ActiveRecord::Base has_may :bars scope :has_no_bars, includes(:bars).where("COUNT(foo.bars) = 0") end But I don't understand the appropriate syntax. Any help? Happy to use a MetaWhere solution if easier.

  • Why ADF Developers Should Attend ODTUG This Year

    - by shay.shmeltzer
    If you are using Oracle ADF or planning to pick it up in the next year, I would encourage you to try and attend this year's ODTUG K-Scope conference. If you are not familiar with it, ODTUG - the Oracle Development Tools User Groups - holds a yearly conference that is very technical in nature. It is not a huge conference in terms of the number of attendees, but this just means that you have more opportunities to interact with Oracle ACEs, Oracle Product Managers, and other developers. The conference is known to be a no-fluff, no-marketing, technical conference. This year however there is one key new thing that should be of interest to readers of this blog. A new track called the "Fusion Middleware" track has been formed and it has lots of sessions for any level of ADF developer. The track is run by several Oracle ACEs who are also involved in the ADF Enterprise Methodology Group. They have sessions for every level of ADF awareness - from the beginner to the expert, and you can also learn about related technologies such as WebCenter and SOA Suite. Most of the sessions are run by users who share their real world experience with the technology. And me and other PMs will also be running a few sessions and hands-on labs there. Check out the list of sessions in the Fusion Middleware track. And don't miss the Sunday symposium too.

  • Is my JS/Jquery methodology good?

    - by absentx
    I always struggle with which of the stack sites is best to post "questions of theory" like this, but I think programmers is the best, if not, as usual a mod will move it etc... I am seeking critique on what has become my normal methodology of writing javascript. I have become heavily reliant on the Jquery library, but I think this has helped me learn the native language better also. Anyways, please critique the following style of JS coding...buried are a lot of questions of scope, if you could point out the strengths and weaknesses of this style I would appreciate it. var critique ={ start: function(){ globalness = 'GLOBAL-GLOBAL'; //available to all critique's methods var notglobalness = 'LOCAL-LOCAL';// only available to critiques start method //am I using the "method" teminology properly here?? $('#stuff').on('click','a.closer-target',function(){ $target = $(this); if($target.hasClass('active')){ $target.removeClass('active'); } else{ $target.addClass('active'); critique.madness($target); } }) console.log(notglobalness+': at least I am useful at home'); console.log('note here that: '+notglobalness+' is no longer available after this point, lets continue on:'); critique.madness(notglobalness); }, madness: function($e){ // do a bunch of awesomeness with $e //but continue to keep it seperate because you think its best to keep things isolated. //send to the next function when complete here console.log('here is globalness, which is still available from the start method of critique!! ' + globalness); console.log('lets see if the globalness carries on to a new var object!!'); console.log('the locally isolated variable of NOTGLOBALNESS is available here because it was passed to this method, lets show it:'+$e); carryOn.start(); } } //end critique var carryOn={ start: function(){ console.log('any chance critique.globalness will work here??? lets see: ' +globalness); console.log('it absolutely does'); } } $(document).ready(critique.start);

  • How long do you keep session cookies around for?

    - by user246114
    Hi, I'm implementing a web app, which uses sessions. I'm using GWT and app engine as my client/server, but I don't think they're doing anything really different than I would do with PHP and apache etc. When a user logs into my web app, I am using HttpSession to start a session for them. I get the session id like this: // From my login servlet: getThreadLocalRequest().getSession(false).getId(); I return the sessionId back to the client, and they store it in a cookie. The tutorial I'm using sets this cookie to 'expire' in two weeks: Cookie.write("sid", theSessionId, 1000 * 60 * 60 * 24 * 14); // two weeks Here's where I'm confused: if the cookie expires in two weeks, then my user will go along using the webapp happily, only to one day browse to my site and be shown a login screen. What are my options? Can I just set no expiration time for this cookie? That way the user would have to explicitly log out, otherwise they could just use the app forever without having to log back in? Or is there a better way to do this? I can't remember sites like Twitter having ever asked me to log back in again. I seem to be permanently logged in. Do they just set no expiration? The webapp isn't protecting any sort of highly sensitive data, so I don't mind leaving a cookie that doesn't expire, but it seems like there must be a better way? This is the tutorial I'm referencing: http://code.google.com/p/google-web-toolkit-incubator/wiki/LoginSecurityFAQ Thanks

  • How to Disable Ubuntu’s Guest Session Account

    - by Chris Hoffman
    Ubuntu and Linux Mint come with a “Guest Session” account, which anyone can log into from the login screen – no password required. If you’d rather restrict access to your computer, you can disable the guest account. This guest account is locked down and changes to it don’t persist between sessions – everyone that logs in gets a fresh desktop. Still, you may want to disable it to prevent other people from using your computer.

  • Retrieve a command from another, remote bash session

    - by Oli
    So I was on our laptop, SSH'd into my desktop, dropping some mad bashfu skill. There was one command I ran which was particularly skilful. I'm now about minute walk from the laptop and I really want that command here on my desktop, so that I can run it again. I realise I've already spent more time that it would have taken to rewrite it, but this has raised a common issue I have with bash history. I know I can force it to update each command, but I haven't... so: Is there any way to get a history from a different, live bash session?

  • Slides and links from Cloud Computing Congress session on Windows Azure Platform

    - by Eric Nelson
    On Tuesday (16th March 2010) I presented on Azure to a none technical audience at the Cloud Computing Congress. Great audience, lots of folks, lots of questions during and after – although it did feel odd to do a session with no code :-) Lots of people asked me for my slide deck – which is a 30minute none technical overview. I will get it on my slideshare.net (which is being temperamental) but in the meantime I have hosted it on skydrive. or download link.

  • What is "Unlock keyring" and how do I get rid of it?

    - by cipricus
    (In my case this message never appeared before installing Ubuntu One - see this question). Can I use Ubuntu One and avoid being prompted each time like this? I use Lubuntu 12.04. Edit: After exchanging comments I add the supplementary info: I am asked for password and to select session if I log out and in (auto-login is NOT set). Ubuntu One is installed but set NOT to start with session. Keyring appears nonetheless. Before installing Ubuntu One this didn't happen. Also, following the advice of con-f-use, I have entered ps -A | grep -i ubunt[u] in terminal, and got 2346 ? 00:00:01 ubuntuone-syncd, which means that ubuntuone is running when it was not supposed to.

  • 12.04 64 bit: Keybord not responding for about 20 seconds at startup/beginning of session

    - by Danilo
    I am running Ubuntu 12.04 64bit. When I get at the login screen and try to type the password for my user, I cannot type anything for about 20 seconds. After that, the keyboard starts responding and everything works fine. Mouse is responding normally as well as all buttons of the login interface (time/calendar, session selection (Unity/Unity 2D), etc.). What could be the reason for this behavior? How can I solve this temporary freeze of the keyboard so that I can type my password immediately without having to wait each time? Thanks for your time. EDIT: I tried auto login, but the problem is still there: the Desktop loads but even there, if I try to type something in the dash or anywhere else, I must wait about 20 seconds before I can actually start typing. Can the issue be related to some keyboard modules that get loaded little bit "too late"?

  • How to make JWM work in Ubuntu 12.04?

    - by alba
    I have installed the JWM on Ubuntu 12.04 via the Software Centre, but it doesn't work. When I choose the JWM session from LightDM, it only shows a black screen. It worked when I had another computer with Ubuntu 11.10, where I had the same problem after the JWM installation. But once, by chance, I chose to start JWM from a Fluxbox session. And after that, i was able to start JWM also from LightDM. But this solution does not work for me on Ubuntu 12.04. JWM never starts.
